Description: CB10-277 is a synthetic derivative of dimethylphenyl-triazene related to dacarbazine, with antineoplastic properties. Related to the agent dacarbazine, CB10-277 is converted in vivo to a monomethyl triazene form that alkylates DNA, resulting in inhibition of DNA replication and repair; in addition, this agent may act as a purine analogue, resulting in inhibition of DNA synthesis, and may interact with protein sulfhydryl groups.
